How long should a properly maintained chain last? I seem to have short life spans for my chains. Yes, I do keep it cleaned and lubricated.

How's that for an answer! There are a lot of factors that affect chain life. What kind of lube, riding style, cross-chaining, weather, etc. How long are your chains lasting?

Just comparing Record 9 and SRAM R99, I find the Campy chain lasts about 50% longer than the SRAM. If you get caught in the rain, ride in dusty conditions, do a lot of climbing/sprinting, are stronger than average, have a rough pedaling style, etc. these can all reduce chain life. I think Shimano chains don't last nearly as long as Campy, based on the mileage people report. Finally, a lot of people say they clean and lube well, but in fact they don't really. Any lubing practice that allows gunk to build up on the chain is a short road to rapid chain wear - the gunk acts as a grinding compound.

They say you should get at least 1500 miles out of a chain with reasonable maintenance along the way. I have had both Campy and Shimano and got much more than 1500 miles on the chains. I must say that with the Campys it is hard to wear them out. Over the past two years I have switched entirely to Campy products and can't comment on recent Shimano chains. Don't think I'd go back, either.

I just removed the OEM shimano 73 chain. It only got roughly 300 miles. That seems like crap. I use on of those park chain checkers to monitor my chain wear and replace when it hits 1. I have had cranks wear out due to lack of lube and using a work out chain on my mountain bike. ( I am new to road biking and have had most of my experience with mountain bikes.)

I take really good care of my chains. I keep them gunk free and well lubed. It is really easy on a road bike. I get enough cleaning a lubing experience on my mountain bike. It is rather dusty here in Texas though.

I have just switched over to SRAM since I have had good luck with them on mountain bikes.

I have a new Ultegra Driveline. After 1700 miles, I am reading only .005" of stretch on the HG-72 chain over a span of 20 links. I clean and lube the chain about every 500 miles. Maybe once the cassette and chainrings begin to wear, it accelerates chain wear?
